Europe's Coldest Cities in Summer. Europe's northernmost city has the continent's coolest summers. No other major city stays anywhere as tepid as ReykjavÃ­k, Iceland, where maximum temperatures average a meagre 12.7 degrees Celsius (54.8 degrees Fahrenheit). That's over five degrees Celsius (10 Â°F) lower than the next coldest city, Leeds.
First, have realistic expectations â nowhere in Europe is tropical in the winter. The Canary Islands are the warmest place in Europe, and January temperatures will be in the mid-50s to mid-60s (12-18 C). So donât look for summer â look for spring. And thatâs not a bad thing.
